The fire-resistant performance of metal partitions on mezzanine platforms is one of the key elements in ensuring warehouse safety. The following is a detailed analysis of its fire-resistant performance:
I. Material Properties and Fire Rating
- Non-combustible material: Metal partitions (such as steel partitions) are usually made of inorganic materials or fire-treated metals, and their combustion performance reaches the national A-level standard (non-combustible). At high temperatures (such as 1000℃ flame for 3 hours), the partition can still maintain structural stability, without deformation or combustion support.
- High temperature resistance and corrosion resistance: Metal partitions have excellent bending strength and corrosion resistance. Even in a water-saturated state, the bending strength can still be maintained above the qualified standard (such as above 6 MPa), and the moisture absorption deformation rate is low (<0.35%), ensuring structural stability during long-term use.
II. Fire Prevention Function and Role
- Blocking the spread of fire: Metal partitions can serve as core components of fire-resistant zones, effectively isolating the fire source and limiting the spread of fire during a fire. For example, in areas with dense cables or mezzanine racks, partitions can contain flames to a local area, buying time for evacuation and fire extinguishing.
- Delaying fire development: Even if the partition itself does not burn, its high-temperature resistance characteristics can delay the softening or collapse of the metal structure, thereby extending the fire resistance limit. Some products remain intact in the 3-hour fire test, meeting national standards.
III. Application Scenarios and Advantages
- Adaptability to mezzanine platform racks: Metal partitions are often used in the fire-resistant zone design of mezzanine platform racks, forming fire-resistant partitions or troughs through cutting and fixing (such as steel brackets or expansion bolts). Its mechanical strength can bear the pressure of goods while meeting fire prevention requirements.
- Environmental protection and economy: Compared with other fire-resistant materials (such as fire-resistant coatings), metal partitions do not require frequent maintenance and are inexpensive (approximately 20 yuan/square meter), with high cost performance. In addition, its non-toxic and odorless characteristics are suitable for public places.
IV. Construction and Maintenance Points
- Installation specifications: Partitions must be fixed with steel structures, joints must be sealed with organic sealant, and the surface of the steel frame should be coated with fire-resistant paint to enhance the overall fire resistance.
- Regular inspection: Pay attention to whether the partition is aging, rusted, or damaged, and repair or replace it in time to ensure that the fire-resistant performance remains effective.
Mezzanine platform metal partitions, with their non-combustibility, high strength, and corrosion resistance, have become an important choice for warehouse fire prevention design. Their core value lies in providing key protection for personnel evacuation and fire control through physical barriers and fire resistance. In practical applications, local fire codes should be combined, fire-resistant zones should be reasonably designed, and the standardization of construction and maintenance should be ensured.
